@heinrich5991 this might interest you, I think you asked me for something like this for vanilla some time ago: https://github.com/H-M-H/bundle_libs

H-M-H/bundle_libs

bundle_libs - Easily deploy dynamic/shared libraries alongside your App on macOS

When i vote for the maps Injection and Injection 2, the server switches to moderate with caventure map. Seems like maps are missing?

05:36

same goes for a lot of maps

<deen> Apparently setting different compiler optimizations with the gcc version in debian 9 makes the server use 100% cpu even when nothing is going on :D

06:46

<deen> heinrich5991: i think it has to advance the game state?

06:46

<deen> heinrich5991: or you mean just stay at the same tick?

<heinrich5991> deen: staying at the same game tick

08:09

<heinrich5991> but I haven't measured how much CPU it actually costs

08:10

<heinrich5991> the higher optimization levels probably exposed bugs, are there coredumps?

08:11

<deen> probably, but I didn't care to collect

08:11

<deen> should be very easy to reproduce

08:11

<deen> just compile with -Ofast -march=native -mtune=native -flto=10

08:12

<deen> I remember the first ones didn't cause any harm in the past, so it's probably -flto=10

08:12

<heinrich5991> don't enable -Ofast, it disables standards compliance

08:12

<heinrich5991> (and also -ffast-math)

08:13

<heinrich5991> yea, flto might be causing it, lemme see

08:18

<eeeee> are we clean in -fsanitize=address and -fsanitize=undefined ?

08:19

<deen> probably not

Can u guys played ddnet in a window? I dont have fullscreen checked but still im playing with fullscreen i can check and uncheck it in settings nothing happenes

<deen> even after restartin the client?

08:22

<deen> and choosing a smaller resolution?

08:22

<deen> and using the most recent client version?

Y

08:23

Idk

08:23

xD

08:23

Wait

I got it

<heinrich5991> debug info of course destroys the bug :/

<deen> heinrich5991: fixing sanitizer warnings like eeeee suggested could help

09:33

<deen> I didn't know posix has asynchronous I/O

09:38

<deen> could be nice for logging and writing demos

09:38

<deen> not sure how reasonable the apis and the corresponding windows ones are though

<Learath2> deen: loading the map Injection seems to crash the server

or the map is missing or sth

<heinrich5991> asynchronous IO was poor on POSIX IIRC

11:10

<deen> Learath2: well, debug it? you have ssh access, right?

11:10

<Learath2> yeah checking it out

11:11

<Learath2> can't check dmesg nor know where we put coredumps tho

11:11

<Learath2> but fear not, will figure it all out :)

11:11

<deen> coredumps in same directory

11:11

<deen> use root for dmesg

11:11

<deen> Most likely it's still failing because of old server versions compiled with lto

11:12

<Learath2> dont think i have root on GER

11:12

<Learath2> yeah lemme check the lto thing first

11:12

<deen> tried it on an empty new serveR?

11:13

<deen> ah shit

11:13

<deen> it still compiles with lto

11:13

<deen> on GER

11:13

<deen> let me fix that quickly

11:14

<Learath2> deen: which script compiles the server?

11:14

<deen> I've done that already

11:14

<deen> cd src; ./build.sh

11:15

<deen> I think I forgot to copy the new build.sh on GER, oops

11:16

<Learath2> deen: also servers/test/data/maps seems empty

11:16

<Learath2> no idea what happened there

11:16

<deen> yeah, servers were restarted

11:16

<deen> to fix vulnerability

11:16

<deen> needs to be mounted again

11:16

<deen> see run-all.sh

11:18

<Learath2> \o/

11:19

<deen> (I guess the mount fails when ddnet.tw is still offline so it never remounts it later)

11:19

<Learath2> could mount it in a loop until it succeeds i guess

11:19

<deen> or use automount

<Learath2> does automount make sure it mounts even?

11:28

<deen> i think it blocks access until it's mounted, but not sure

What techniques would you say are easier with weak hook

that thing where you drag someone who is above hook thrus and have to go below obstacles

13:49

the bigger the obstacle the easier it is with weak i guess

<deen> @Dr.Jekyll for me everything was easier with weak since I always played with it

14:29

<deen> so you just get used to it

sure theres a big aspect of getting practice

14:29

but strong hook is objectively better at some things

Embedded image

14:30

anyone know how to fix this bug?

14:30

might have to do with quads and clipping

what bug

needs a red mspaint circle

the white stripes in the middle of the screen

delete the quad .. ?

14:33

whats it supposed to look like

this is how it usually looks

borderfix/dilate?

Image attachment

what map

run_down_the_rabbithole.map

5.97 MB

it is online ?

14:36

somewhere

@Savander i think unique servers had it

yes

yea im there

i dont see the smudge

@jao well the natural question is, when does it happen?

randomly on maps that have clipping and quads, not on every map

but does it always look like that for you or do you have to move around or sth like that?

14:41

is the smudge fixed right there as you move or does it move with you?

ddnet-live - Live Streaming Infrastructure

15:40

it worked ?

what's with ddnet-live?

just found it

yes, it worked

15:41

it just had no use

:<

15:41

im curious how it looked xD

just a video of the game

15:41

chat was the interface to control it

Does it consume a lot resources?

yeah, because intel is stupid

:/

15:43

maybe you could run it on gpu ?

my intel cpu has an h264 encoder included, but you can only access it through some proprietary media library

15:43

so it only works on 1-2 linux distributions in some specific versions

15:43

totally ridiculous

you run it on vps ?

https://hookrace.net/blog/ddnet-live/

15:45

nope, at home

have you tried AMD Hardware Encoder or from nvidia ?

nope, i don't own any gpus

15:46

only included intel ones

15:47

they are probably really bad quality for the bitrate anyway

Hmm, understand :/ because it could be muuch faster

speed is not the problem, it just consumes a few cpu cores and 10 W or so

I was using it while streaming

15:48

i think, 3k bitrate is optimal

15:48

for hd

15:48

i mean, good quality, without smoothing

try out veryslow compared to veryfast in x264 with 3000 bitrate and compare the result

15:49

there can be HUGE differences at same bitrate

and that weird mosaic

always depends on how much cpu you want to use

yea, that's right

I never went below "fast" setting

15:51

it was too hard for my computer to stream and run game smoothly

15:51

there is even option "placebo"

15:53

Have you ever bought a network card? I have to buy 1gbps one. Maybe you have any recommendation

why do you have to buy one?

15:56

Intel is usually the safe guess

Cuz, my current network card

15:56

doesn't support ISP's router

huh?

15:57

Maybe use another cable

which they gave me to handle fiber cables

15:57

i tried

15:57

A looot things

15:57

and the only one which worked

Never heard about something like that

is usign my old router

15:57

as a bridge

15:57

I was talking about it a month ago

are you sure that's not a software problem?

15:58

dhcp?

that my connection has incredibly long time to estabilkish connection

15:58

I'm not sure

15:58

I made a topic

15:58

https://www.tenforums.com/network-sharing/92817-long-establishing-connection-router-windows-10-a.html

Long establishing connection to the router on Windows 10 - Windows 10 Forums

Hello, I have a problem with establishing a connection with the router. Windows for a long time, after booting computer says that my cable is not plugged in. The time between establishing and booting

incompatibility between network devices should not happen nowawadays in 1gbit/s

on windows 10 forum

maybe in 10-100 gbit/s

i tried a lot things, nothing helped

15:59

even my ISP told me that

tried linux?

"hey, buy new network card"

15:59

nope, i didn't

15:59

i know that while booting

15:59

network is estabilished

15:59

then don't

if it works immediately in safe mode, then it's clearly a software problem

but, it works perfectly with 100mbs router

15:59

so its weird

try removing the network driver

yea i tried

15:59

i even formated computer

15:59

and, it stopped works in safe mode (edited)

15:59

as well

settings of your network driver

16:00

and fumble around there

yea i tried change negotiation settings

16:00

to force 1gbs port

16:01

i have idea

try installing another driver

i will download live linux

16:01

and try it there

and disabling dhcp

I disabled DHCP. I even forced static IP

16:01

to use routers gateway

16:01

etc

turn off all other software?

yup, i did clean run

16:02

only windows

16:02

still nothing

and I think windows has something between safe mode and normal mode

16:02

where you can select which components to load and which not

16:02

or at least old versions had that, could be used to bisect where the problem comes from

Yes, i disabled every external programms services

16:02

disabled all programs on startup

16:03

and i have to say, that the problem were even after fresh installation

16:03

so i bet, it's not because of external programs/drivers

16:03

i tried at least 2 network drivers

16:03

the built-in and those from motherboard website (asrock)

might be the same

then i don't know which one i should download

D

16:04

PCI\VEN_10EC&DEV_8168&SUBSYS_81681849&REV_06

16:07

does live debian will support network connectio ?

16:07

https://www.debian.org/CD/live/

yes

debian 9.1 (y)

16:08

last time i used debian 7

16:13

installing packages on live ver, will do it to ram ?

what else do you expect?

16:14

a cloud disk?

would be cool

16:14

no, i was thinking if it would store it on disk or

16:14

somehwere

16:15

in CPU memory maybe

yeah, just format the entire disk

16:15

cpu memory?

16:15

cache is not thaaaat big yet I think

<Savander_d> :D

16:33

<Savander_d> it works via live Debian

shaders ?

<heinrich5991> programs that run on gpus

20:09

<Learath2> damn i wanted to do that, would have been good practice

that is indeed funny, I am also creating some stuff to run on my gpu atm (cuda & opengl maybe also opencl later), it is not releated to ddnet though

Nice HMH alive feelsamazingman

feelsamazingman

has someone tried http://nanapro.org and know if it's good? (gui-library)

20:55

https://github.com/ocornut/imgui this one looks good :o

imgui - Bloat-free Immediate Mode Graphical User interface for C++ with minimal dependencies

<heinrich5991> both look nonnative

https://github.com/vurtun/nuklear

nuklear - A single-header ANSI C gui library

20:58

yep

20:58

can't decide what to use :D

<heinrich5991> you don't want native-looking UI?

imgui is cute

last looks best

nah, thosei sent look modern

20:59

if i would want native looking ui i would use c# wpf..

the last one looks nice but i've never used it

21:00

imgui is nice for quickly whipping up debug menus

yep, thats what looks like from their images

there is any gui that can be customized with css?

21:00

:d

electrum or someshit like that

u mean electron

21:01

and it is nodejs in a desktop enviroment

21:01

so html

then you don't have likmits?

https://electron.atom.io/

Build cross platform desktop apps with JavaScript, HTML, and CSS.

21:02

(pss, i think discord uses electron)

; O?

(yep, scroll down)

<heinrich5991> qt and gtk can be customized by css I think

21:02

<heinrich5991> and aren't even as resource-heavy as electron

there was some other thing that turns a website into a native app by bundling chromium with it

21:03

stupid stuff imho

^

discord

21:03

definitely is built with electron

<heinrich5991> yes :(

http://www.wasz.ovh/img/0cg23zo785038

21:03

It's not that bad imo

21:03

what

it's like having a game open 200mb~

what with my domain

<heinrich5991> discord is the program that uses the most memory, right after my browser

gotta love chromium using as much ram as Maya

<heinrich5991> (discord uses 300MB for me)

the nuklear gui lib i sent is made with ansi C

21:05

"No dependencies (not even the standard library if not wanted)"

21:05

xD

a nice sentiment

21:06

would use that

<heinrich5991> that must be a lie :D you can't do a UI without using winapi on windows

23634 lines of code

<heinrich5991> tw level I think

21:06

<heinrich5991> tw has ~35k?

https://github.com/vurtun/nuklear/blob/master/nuklear.h

nuklear - A single-header ANSI C gui library

hmm too many lines of code

you need to #include the winapi right?

21:09

i cant find any include with it

<heinrich5991> how do you expect to make UI without dependencies?

21:16

<heinrich5991> the C standards provides no facilities to do so

21:16

<heinrich5991> -s

i see, it is a embeddable user inerface

21:18

which means it needs a renderbackend or OS window

@Savander there is also Qt, you can style it with QSS: https://doc.qt.io/qt-5/stylesheet.html

or just write QML

at least we are lucky and do not have to deal with Vulkan

is vulkan harder than opengl?

well, yes it is far more complicated, pretty bloated, i mean you need ~1k lines to get a damn triangle on your screen...

23:31

https://vulkan-tutorial.com/Drawing_a_triangle/Swap_chain_recreation

23:31

https://vulkan-tutorial.com/code/swap_chain_recreation.cpp

as far as I understand it is lots of boilerplate code, so for two triangles you fortunately wont need 2k lines of code, I might even give Vulkan a try when Qt 5.10 is out as it will include some wrapper to reduce the ridiculous amount of code to set things up
